In which position is the sleeper stretch performed?

The sleeper stretch is specifically designed to target the shoulder’s internal rotation by stretching the posterior capsule and enhancing mobility of the glenohumeral joint. It is effectively performed in a side-lying position with a roll placed under the axilla. This positioning facilitates the necessary tension on the shoulder joint while maintaining a neutral spine and alignment of the body.

When executed correctly in this position, individuals can safely achieve a stretch that encourages optimal range of motion without overly compromising other joints or muscle groups. The roll under the axilla provides additional support and allows for an effective stretch through the posterior shoulder, which is essential for various athletic movements.

Other positions, such as standing or sitting, do not provide the same level of targeted stretch to the necessary structures in the shoulder. Lying prone would also not accomplish the goals of the sleeper stretch as effectively, as it alters the mechanics of the shoulder and limits the stretch on the posterior capsule.
